Drone Position Source in Mission Planner with Single vs. Dual GPS Setup

ArduCopter Copter 4.5

Hi everyone,

In Mission Planner, is the displayed position of the drone based on the GPS module or the IMU?
Also, does this change when using a single GPS versus a dual GPS moving base configuration?

Thanks in advance!

MP displays canonical vehicle position (typically EKF), exact position will depend on configured offsets, which GNSS receiver is used as reference is configured in Ardupilot by one of GPS_* parameters, two receivers in moving baseline configuration should provide cohesive position information matching configured offsets, otherwise MB won’t be used.

Have you read through the ardupilot documentation online?
